Hello majid.ebru!
You need configure jEditText. Example [from "AppDemo1"]
object jEditText1: jEditText
LayoutParamWidth = lpMatchParent
LayoutParamHeight = lpOneFifthOfParent
InputTypeEx = itxMultiLine
MaxTextLength = 800
ScrollBarStyle = scrlInsideInset
MaxLines = 10
HorScrollBar = False
VerScrollBar = True
WrappingLine = True
Editable = True
NOTE: You can use jWebView to output formated text !
ex. jWebView1.LoadFromHtlmString(......);
jWebView1.LoadFromHtmlFile(......);
